JST, CREST国際ワークショップ

Oct 21, 2014

In late October, the JEDI-System Project, headed by Professor Hidekatsu Yamazaki, joined with Dr. S. Lan Smith, the principal investigator in a JST, CREST project at JAMSTEC, in order to host an workshop titled 'Advances in the Plankton Ecosystem Model and the Evaluation of Biodiversity'. The other conveners included Professor Simon Levin (Princeton University), Professor Ken Denman (University of Victoria), and Professor Chih-hao Hsieh (National Taiwan University). The workshop was held at Tokyo University of Marine Science and Technology's Rakusui Hall.

OCEANS Underwater Observatory Deployment

Featured Article

Aug. 12, 2014

OCEANS is an underwater observatory system that enables real-time viewing of what is happening in the ocean around Oshima Island, Japan (Fig. 1). By taking advantage of the live data, we can discover what kinds of fish swim through the area or what kinds of plankton live in a parcel of seawater. For example, our research team found that highly dense mysida aggregations appear (Fig. 2), indicating a biologically rich environment around Oshima Island.

2014 JST, CREST Site Visit @ Oshima

May 30, 2014

In early May 2014, Professor Koike, the research supervisor from JST, CREST, visited Izu-Oshima Island to inspect the OCEANS site (Oshima Coastal Environmental data Acquisition Network System). The main topic of discussion was how to deploy the cable and the node.

Mandal Paper Published in PLOS ONE

May 2, 2014

The highly respected open-source scientific journal PLOS ONE has published a JEDI-System paper by Sandip Mandal, Christopher Locke, Mamoru Tanaka, and Hidekatsu Yamazaki entitled "Observations and Models of Highly Intermittent Phytoplankton Distributions." The paper, accepted March 20, 2014, applies a new planktonic ecosystem modeling method called the closure approach and was written as part of the JEDI-System subprogram S2. New Planktonic Ecosystem/NPZ Model.

ADCP Recovery and Analysis @ Oshima

March 17, 2014

On November 6, 2013, the JEDI-System project deployed an ADCP on the ocean floor to gather preliminary data about the Oshima Coastal Environmental data Acquisition Network System (OCEANS) installation site. The OCEANS cabled observatory (CO) is scheduled to be placed on the ocean bottom at 20 meters below the surface and will measure various physical, chemical, and biological parameters.

JST, CREST JEDI-System Project Meeting @ TUMSAT

December 2, 2013

In early December 2013, the JEDI-System team held a progress report meeting at the Tokyo University of Marine Science and Technology. The primary purpose of the meeting was to discuss advancements thus far and to prepare for the January JST, CREST research area meeting.

ADCP Test & Preliminary Underwater Inspection

Preliminary Underwater Inspection @ Oshima

November 5-8, 2013

In a meeting room of an oceanfront office, Dr. Scott Gallager, an associate scientist visiting from WHOI, spoke about the obstacles to the establishment of an underwater observatory. The specific topic that day was the fluidity of the sand on the ocean floor.

R/V Seiyomaru Embarks for Ocean Observation

Ocean Observation @ Oshima

June 20-24, 2013

One of aims of the JEDI-System project is the classification of plankton. Not much is known about the plankton species composition around Izu-Oshima, so in late June, the JEDI-System team set sail on Tokyo University of Marine Science and Technology's R/V Seiyomaru to conduct surveys and take samples. Specifically, the team researched chlorophyll concentration and plankton species composition.

The results from the R/V Seiyomaru cruise showed that chlorophyll concentration of picophytoplankton at a 10-m layer was several times higher than that in December 2012.

2013 JST, CREST Site Visit @ TUMSAT

May 31, 2013

At the end of May 2013, the research supervisor of the JEDI-System project, Professor Isao Koike, visited Tokyo University of Marine Science and Technology to discuss the project's progress and plans.

The JEDI-System project is a JST, CREST five-year project, which means that it will be evaluated again after three years.

JEDI-System: New Name Revealed

2013 Kick-Off Meeting @ TUMSAT

April 25, 2013

At the beginning of the fiscal year, the project team held the 2013 kick-off meeting at Tokyo University of Marine Science and Technology.

The meeting started off with the reveal of the project's new name: "JEDI-System," which stands for "Joint Environmental Data Integration System."

The Project’s First Kick-Off Meeting

2012 Kick-Off Meeting @ TUMSAT

October 25, 2012

The ocean modeling and monitoring project held its first kick-off meeting in late October 2012. At the meeting, the project team, which is composed of members from institutions across Japan and the world, clarified the role of each group in the team.

JST, CREST Funding Commencement

October 1, 2012

In 2012, our team's research plan, which includes a cabled ocean observatory and a new planktonic ecosystem model, was chosen as a JST, CREST-funded project.

The project is officially titled "Novel technologies to evaluate multi-scale variations of pelagic marine communities and biodiversity under the influence of the Kuroshio and internal waves in coastal habitats" and is part of the research area entitled "Green innovation: Establishment of core technology for the preservation and regeneration of marine biodiversity and ecosystems."
